TERMINAL.

Application filed May 29, 1915.

To all whom it may concern:

Be it known that I, HOWARD B. SHERMAN, a citizen of the United States,residing at Battle Creek, in the county of Calhoun and State ofMichigan, have invented certain new and useful Improvements inTerminals; and I hereby declare that the following is a full, clear, andexact description thereof, reference being had to the accompanyingdrawings, which form part of this specifica tion.

This invention relates to so called ter-v minals attached to the end ofa bunch of wires or a wire cable, to facilitate making electricalconnections therewith, and in particular is an improvement upon theterminals shown in the application of Herbert B. Andrews filed April 19,1915, Serial No. 22,446, but is also useful in connection with otherterminals formed of metal-tubing or sheet metal and having one endflattened to form a shank.

The objects of my invention are to insure a good connection between theflattened portions or walls of the shank; to prevent solder or othermetal used in sweating an electric cable end into the terminal socketescaping through the opening in the shank of the terminal; to preventmoisture entering the shank at such opening and to make and maintain abetter electrical connection between the walls of the shank.

-I will describe the invention as applied to terminals such as shown insaid Andrewss application and summarize the invention in the claim.

In the drawings :Figure 1 is a side view of an Andrews terminal asimproved by and embodying my invention. Fig. 2 is a top plan viewthereof. Fig. 3 is a longitudinal section on line 8-3 Fig. 2. Fig. 4 isan enlarged transverse section on line 44 Fig. 2. Fig. 5 is an enlargedtransverse section, illustrating a modification of the construction.

The terminals are preferably made from a metallic cartridge having aninternal diameter corresponding to that desired for the socket of thefinished terminal, and the closed end of the cartridge being flattenedby compressing the wallsthereof by any suitable means, such flattenedportion as indicated in Figs. 1 and 3 forming the shank 1 of thefinished terminal and the unflattened tubular portion thereof formingthe socket l thereof, said shank and socket be- Specification of LettersPatent.

ing integral. When formed from a cartridge as described the shankportion has its outer end rounded as indicated in Fig. 2. The shank 1has an opening indicated at 1 for engagement with a retainer, such, forinstance, as a binding post, or any suitable fastening or supportingdevice. Such terminals are usually secured to the cable by soldering orsweating the terminal thereon in the usual manner. If solder shouldexude into the opening 1 it would clog said open- 7 ing, and have to beremoved before the terminal could be properly attached to theretainer,'thus causing considerable annoyance and delay.

It will be observed by reference to Fig. 3 that if the socket 1 wasfilled with hot solder such solder might pass through the shank to theopening 1 particularly if the upper and lower collapsed walls of theshank should be slightly sprung apart, as might happen in forcing theend of a cable into the socket.

To prevent solder escaping into or clogging the opening 1, or moistureentering the socket or shank through such opening, the space between theupper and lower walls of the shank indicated by the line S ishermetically closed around the periphery of the opening preferably byinserting a ferrule 2 in said opening and flanging the upper and loweredges of this ferrule over the top and bottom walls of the shank asshown in Figs.

3 and 4, by suitable tools, preferably using sufficient pressure toembed the flanges 2 of the said ferrule into the upper and lower facesof the shank so as to keep the shank smooth surfaced.

In some instances I may form the ferrule integral with one wall of theshank, as indicated in Fig. 5, by protruding metal from such memberthrough and around the edges of the opening in the opposite member ofthe shank, as indicated at 3 in Fig. 5, and spreading or flanging theupper edge of this protruding portion over the other member as indicatedat 3 in Fig. preferably compressing the same so that the shank will besmooth surfaced.

While I propose to apply the invention particularly to the Andrewssterminal as above stated, it could also be applied to other terminalsmade from short sections of pipe each having one end flattened, or fromsheet metal bent into proper form. The invention also serves as a meansfor more firmly uniting the Walls of the shank together at and aroundthe opening, and. prevents separating of the shank When a cable end isforced into the terminal and makes or maintains a better electricalconnection between the Walls of the shank and the retainer.

What I claim is:

A terminal consisting of a metallic cartridge open at one end andclosed. at its other end, the open end forming a socket and the closedend being flattened to form a double Walled shank, said shank having anopening therethrough for connection with a retainer,
